MODEL ZUPČASTO-KAIŠNOG PRENOSNIKA

Abstract

This paper deals with kinematic analysis of timing belt transmissions contacts, as well as, with detailed analysis of timing belt model. Timing belt tooth goes into contact with a drive pulley, stretched to the maximum, because of the previous tension. When the contact begins the peak of the belt tooth makes the contact with the outer surface of the pulley teeth. The process of the teeth entering into the contact zone is accompanied with the relative sliding of their side surfaces and appropriate friction force. Belt material properties, a generally existing pitch difference as well as friction forces between belt groove and pulley top land are taken into account.
